Description

The present disclosure generally relates to an air distribution nozzle, an aircraft including an air distribution nozzle, and / or a method of utilizing an air distribution nozzle.

Distributing nozzles can control, guide, and / or regulate the flow of fluids such as air and can be used in a variety of applications. As an example, the use of air distribution nozzles to form and / or define an air curtain can allow and / or facilitate different environmental controls, for example, on each side of the air curtain. As another example, an air distribution nozzle can be utilized to regulate the air flow in the aircraft. In certain examples, air distribution nozzles are used to form and / or define an air curtain in the aircraft cockpit, allowing independent environmental control of the aircraft's pilot and co-pilot seat areas. And / or can be facilitated. Traditional air distribution nozzles are relatively complex, utilize a significant number of individually manufactured and later assembled parts, and / or are relatively expensive. Therefore, there is a need for improvements in air distribution nozzles, as well as aircraft including improved air distribution nozzles, and / or improved methods utilizing improved air distribution nozzles.

Aircraft including air distribution nozzles, aircraft including air distribution nozzles, and / or methods of utilizing air distribution nozzles are disclosed herein. The air distribution nozzle includes an elongated inlet chamber, an elongated outlet chamber, a tapered elongated slot, an inlet port to the elongated inlet chamber, and an elongated outlet port from the elongated outlet chamber. The elongated entrance chamber extends along the length of the entrance chamber. The elongated exit chamber extends along the length of the inlet chamber. The tapered elongated slot extends between the elongated inlet chamber and the elongated outlet chamber, interconnecting the elongated inlet chamber and the elongated outlet chamber with respect to the fluid. The inlet port is configured to receive the inlet fluid flow in the inlet flow direction along the inlet flow axis. The elongated outlet port is configured to drain the outlet fluid flow along the outlet flow axis in the outlet flow direction. The outlet flow axis is directed at the skew angle with respect to the inlet flow axis.

The aircraft includes an air distribution nozzle and an air supply conduit that provides an inlet fluid flow to the inlet port. The method comprises bringing the inlet fluid flow through the inlet port to the elongated inlet chamber along the direction of the inlet flow. The method further comprises the step of redirecting the inlet fluid flow within the elongated inlet chamber. Redirection involves redirecting to generate a slot fluid flow through a tapered elongated slot into an elongated outlet chamber. The method further comprises creating a pair of oppositely rotating vortices in the slot fluid flow in an elongated outlet chamber. The method further comprises the step of draining the outlet fluid flow from the elongated outlet port along the outlet flow direction.

It is possible to independently adjust the environment control unit 13 of the FO and the FO's environment control unit 15. In some examples, the air curtain 98 can reduce the possibility of cross-contamination between the co-pilot seat area 12 and the co-pilot seat area 14. In other words, the air curtain 98 is between the co-pilot seat area 12 and the co-pilot seat area 14 by carrying airborne contaminants such as particulate matter, bacteria, and / or viruses on the stream.

With this in mind, none of the structures, functions, and / or features of the air distribution nozzle 100 of FIGS. 2-9 will deviate from the scope of the present disclosure of the aircraft 10 and / or its air distribution nozzle of FIG. It may be included in 100 and / or may be utilized in the aircraft 10 and / or its air distribution nozzle 100 of FIG. Similarly, any of the structures, functions, and / or features of the aircraft 10 of FIG. 1 can be utilized in the air distribution nozzle 100 of FIGS. 2-9 without departing from the scope of the present disclosure.

As shown in FIG. 2 and collaboratively shown by FIGS. 3-9, the air distribution nozzle 100 includes an elongated inlet chamber 150 and an elongated outlet chamber 170. The elongated inlet chamber 150 extends along the inlet chamber length 152 and the elongated exit chamber 170 extends along the inlet chamber length or also along the inlet chamber length, as shown in FIG. .. Further, the air distribution nozzle 100 includes a tapered elongated slot 190.

The air distribution nozzle 100 further includes an inlet port 220 to the elongated inlet chamber 150 and an elongated outlet port 230 from the elongated outlet chamber 170.

The outlet flow axis 92 is directed at a skew angle 96 with respect to the inlet flow axis 72.

During operation of the aircraft 10 including the air distribution nozzle 100 and / or the air distribution nozzle 100, the inlet fluid flow 70 is directed through the inlet port 220 in the direction of the inlet flow and / or along the inlet flow axis 72.

In the elongated inlet chamber 150, the inlet fluid flow 70 can be redirected to generate a slot fluid flow 206 that flows through the tapered elongated slot 190 and / or into the elongated outlet chamber 170. Within the elongated outlet chamber 170, a pair of oppositely rotating vortices 80 can be generated from the slot fluid flow 206 and / or within the slot fluid flow 206. The outlet fluid flow 90, which may be generated from the vortex 80 rotating in the opposite direction, can then be discharged from the elongated outlet port 230 along the outlet flow axis 92 and / or in the outlet flow direction. The generation of the vortices 80 rotating in opposite directions can improve the uniformity of the outlet fluid flow 90, improve the linearity, and / or improve the laminar flow. In other words, the air distribution nozzle 100 can discharge the linear outlet fluid flow 90 and / or the laminar outlet fluid flow 90. Such a configuration can make the outlet fluid flow 90 suitable for a particular application, such as an air curtain 98, as described in more detail herein.

With the above in mind, the air distribution nozzle 100, in the present specification, changes the direction of the outlet fluid flow 90 from the inlet flow direction to the outlet flow direction so as to generate and / or generate, for example, the inlet fluid flow 70.
